TECHNICAL FIELD

This application claims priority to and the benefit of Korean Patent Application No. 10-2014-0150750 filed in the Korean Intellectual Property Office on Oct. 31, 2014, the entire contents of which are incorporated herein by reference.

The present specification relates to a hetero-cyclic compound and an organic light emitting device using the same.

BACKGROUND ART

An organic light emitting device is a kind of self-emitting type display device, and has an advantage in that the viewing angle is wide, the contrast is excellent, and the response speed is fast.

An organic light emitting device has a structure in which an organic thin film is disposed between two electrodes. When a voltage is applied to an organic light emitting device having the structure, electrons and holes injected from the two electrodes combine with each other in an organic thin film to make a pair, and then, emit light while being extinguished. The organic thin film may be composed of a single layer or multi layers, if necessary.

A material for the organic thin film may have a light emitting function, if necessary. For example, as the material for the organic thin film, it is also possible to use a compound, which may itself constitute a light emitting layer alone, or it is also possible to use a compound, which may serve as a host or a dopant of a host-dopant-based light emitting layer. In addition, as a material for the organic thin film, it is also possible to use a compound, which may serve as hole injection, hole transport, electron blocking, hole blocking, electron transport or electron injection.

In order to improve the performance, service life, or efficiency of the organic light emitting device, there is a continuous need for developing a material for an organic thin film.

According to an exemplary embodiment of the present specification, provided is an organic light emitting device including the hetero-cyclic compound represented by Chemical Formula 1.

Specifically, the organic light emitting device according to the present specification includes a positive electrode, a negative electrode, and one or more organic material layers provided between the positive electrode and the negative electrode, in which one or more of the organic material layers include the above-described hetero-cyclic compound represented by Chemical Formula 1.

FIGS. 1 to 3 exemplify the stacking sequence of electrodes and organic material layers of an organic light emitting device according to exemplary embodiments of the present application. However, the scope of the present application is not intended to be limited by these drawings, and the structure of the organic light emitting device known in the art may also be applied to the present application.

According to FIG. 1, an organic light emitting device in which a positive electrode 200, an organic material layer 300, and a negative electrode 400 are sequentially stacked on a substrate 100 is illustrated. However, the organic light emitting device is not limited only to such a structure, and as in FIG. 2, an organic light emitting device in which a negative electrode 400, an organic material layer 300, and a positive electrode 200 are sequentially stacked on a substrate 100 may also be implemented.

As an example, the hetero-cyclic compound represented by Chemical Formula 1 may be used as a material for the electron transporting layer of the organic light emitting device.

Since the hetero-cyclic compound represented by Chemical Formula 1 includes two N (nitrogen) atoms which may attract electrons, the hetero-cyclic compound easily transfers electrons.

Further, the hetero-cyclic compound represented by Chemical Formula 1 has a structural form in which the compound may be stacked between molecules due to the strong planarity when an organic light emitting device is manufactured, and thus the electron mobility is high.

No. 4,356,429 or starburst-type amine derivatives described in the document [Advanced Material, 6, p. 677 (1994)], for example, tris(4-carbazoyl-9-ylphenyl)amine (TCTA), 4,4′,4″-tris[phenyl(m-tolyl)amino]triphenylamine (m-MTDATA), 1,3,5-tris[4-(3-methylphenylphenylamino)phenyl]benzene (m-MTDAPB), polyaniline/dodecylbenzenesulfonic acid or poly(3,4-ethylenedioxythiophene)/poly(4-styrenesulfonate), which is a soluble conductive polymer, polyaniline/camphor sulfonic acid (or polyaniline/poly(4-styrene-sulfonate), and the like.

As the hole transporting material, a pyrazoline derivative, an arylamine-based derivative, a stilbene derivative, a triphenyldiamine derivative, and the like may be used, and a low-molecular weight or polymer material may also be used.

As the electron transporting material, it is possible to use an oxadiazole derivative, anthraquinodimethane and a derivative thereof, benzoquinone and a derivative thereof, naphthoquinone and a derivative thereof, anthraquinone and a derivative thereof, tetracyanoanthraquinodimethane and a derivative thereof, a fluorenone derivative, diphenyldicyanoethylene and a derivative thereof, a diphenoquinone derivative, a metal complex of 8-hydroxyquinoline and a derivative thereof, and the like, and a low-molecular weight material and a polymer material may also be used.

As the electron injection material, for example, LiF is typically used in the art, but the present specification is not limited thereto.

As the light emitting material, a red, green, or blue light emitting material may be used, and if necessary, two or more light emitting materials may be mixed and used. Further, as the light emitting material, a fluorescent material may also be used, but a phosphorescent material may also be used. As the light emitting material, it is also possible to use alone a material which emits light by combining holes and electrons each injected from the positive electrode and the negative electrode, but materials in which both a host material and a dopant material are involved in light emission may also be used.

Hereinafter, the present specification will be described in more detail through the Examples, but these are provided only for exemplifying the present specification, and are not for limiting the scope of the present specification.

The above-described compounds may be prepared based on the Preparation Examples to be described below. Representative examples will be described in the Preparation Examples to be described below, but if necessary, a substituent may be added or excluded, and the position of the substituent may be changed. Further, a starting material, a reactant, reaction conditions, and the like may be changed based on the technology known in the art. A person with ordinary skill in the art may change the kind or position of substituents at the other positions, if necessary, by using the technology known in the art.

The substituent may be bonded by a method known in the art, and the position of the substituent or the number of substituents may be changed according to the technology known in the art.

Manufacture of Organic Light Emitting Device

Comparative Example 1

Trichloroethylene, acetone, ethanol, and distilled water were sequentially used to ultrasonically wash a transparent electrode ITO thin film obtained from glass for an organic light emitting device (manufactured by Samsung-Corning Co., Ltd.) for each of 5 minutes, and then the ITO thin film was placed in isopropanol, stored, and then used.

Next, an ITO substrate was disposed in a substrate folder of a vacuum deposition equipment, and the following 4,4′,4″-tris(N,N-(2-naphthyl)-phenylamino)triphenyl amine (2-TNATA) was placed in a cell in the vacuum deposition equipment.

Subsequently, air in the chamber was evacuated until the degree of vacuum in the chamber reached 10⁻⁶ torr, and then a hole injection layer having a thickness of 600 Å was deposited on the ITO substrate by applying current to the cell to evaporate 2-TNATA. A hole transporting layer having a thickness of 300 Å was deposited on the hole injection layer by placing the following N,N′-bis(a-naphthyl)-N,N′-diphenyl-4,4′-diamine (NPB) in another cell in the vacuum deposition equipment and applying current to the cell to evaporate NPB.

The hole injection layer and the hole transporting layer were formed as described above, and then a blue light emitting material having the following structure was deposited as a light emitting layer thereon. Specifically, the blue light emitting host material H1 was vacuum deposited to have a thickness of 200 Å on one cell in the vacuum deposition equipment, and the blue light emitting dopant material D1 was vacuum deposited thereon in an amount of 5% with respect to the host material.

Subsequently, a compound having the following structural formula E1 as an electron transporting layer was deposited to have a thickness of 300 Å.

An organic light emitting device was manufactured by depositing lithium fluoride (LiF) as an electron injection layer to have a thickness of 10 Å and allowing the Al negative electrode to have a thickness of 1000 Å.

Meanwhile, all the organic compounds required for manufacturing an organic light emitting device were subjected to vacuum sublimed purification under 10⁻⁶ to 10⁻⁸ torr for each material, and used for the manufacture of the organic light emitting device.

Example 1

An organic light emitting device was manufactured in the same manner as in Comparative Example 1, except that the compounds synthesized in the Preparation Examples were used instead of E1 used when the electron transporting layer was formed in Comparative Example 1.

<Experimental Example> Evaluation of Organic Light Emitting Device

For each of the organic light emitting devices manufactured in Comparative Example 1 and Example 1, the driving voltage, the efficiency, the color coordinate, and the service life were measured at a light emitting brightness of 700 cd/m² and evaluated, and the results are shown in the following Table 3. In this case, the service life was measured by using M6000PMX manufactured by Mac Science Co., Ltd.
